invention also relates to the arrangement of the clinlrer removinggrate, the sections of which are housed in the frame oi'i the grate atthe under surface thereof and move withv the grate duringv thehorizontal and verticalr shaking motions and in addition are capable ofbeing adjusted to .provide a 'fuller partial opening for the clinlers totall through.

In the accompanying drawing a constructional form of a grate is shown.Fig. 1being a plan view, Fig. 2 a section on line 9.-2 of Fig. l7 Fig. 3is a sectionon line grate in a closed'position and Figs. i and 5 aresimilar sectional views showing the clinker removing grate in partiallyopen and fully open positions respectively.

-The frame grate R has its sidesbevelled downwards towards the inside.According to the invention the lower surfaces S of the sides of theframe, which rest on the bearers.

P are arcuate. Under'the edge ot the opening in the frame of the grate aguide K` is provided connected to the-frame. in which guide aclinlrer-removing grate V1. V2 consisting of twoor more parts is.slidable The parts of this Aclinker-removinggrate7 when in the positionin which they fill the opening in the frame, lie offset or steppedlwithrespect to each other. vThe position o theupperpartV2 ot theclinker-renioving grate is limited inwardly by a. stop member Z. lowerpart Vj ot the clinlrer-'removing' grate is connected to the shalringorpushing bar T and its motion is transmitted to the upper part V2 b vprojections l. 2 provided on the edges of the parts V1 and V2 engagingone another mutually.

The push bar T may be coupled to `the frame R of the grate. For thispurpose on a shield 1" connected tothe frame oiithe grate staples r areprovided, in which a sliding member 's is capable of sliding trans- 3-3of Fig. 1 with the clinker removing The- 115,363, and in Germany March19, 1925.v

` ber s being slid so thatv its lower edge vrests,

against the bar T,the bar willbe coupled tothe body of the grate, sothat the latter must take part in the. movements of thebar T. Thiscoupling vof the partsfis'eected Aorf/70 the one hand by the'tooth o `onthe bar T and the connection of the latter to the part V1 which issecured relatively to the part V2 by the latter part resting against thestop Z, ensuring the simultaneous movement of the bar and the grates inthe horizontal plane, andon Vthe other hand Vbythe bar T inthe recess ofthe shield-r being coupled by the sliding member sto the body of thegrate in the vertical direction. a v. L p 80 YThe arrangementoperates'in the following manner:y Y

Th bar T being connected in the-manner already described to the body ofthe grate, the latter can be moved iorwardsand Vbaclrwar-ds and alsolaterally. The body of the grate will however also be moved upwards landdownwards, vthrough the arcuate sup- A porting surfaces S sliding on thebearers ofthe grate.

In order to partially or wholly remove the coarse clinker, the-bar T isuncoupled from the body of thegrate R. For this purpose the slidingmember s must be again slid in such a. manner vthat its recess e willlie above 9.5

the bar T. The latter can-then be lifted with its tooth 0 over the loweredge oity the 'slot in the shield r. The displacement of the bar T willthen have no effect on the .body

ofY the grate and will only act on the clinlrer 100 removing grate inthe following manner. On

the bar T being moved-in the direction oit (Fign) the bar V1 will irstbe the arrow w moved alone. When 1t has been slid along till it is belowthe part V2,'the latter will take 105 part in the motion, due tothecoaction of the stop members l, 2, and finally the whole of the openingin the frame of the grate will be left unobstructed (Fig. 5).

On the bar T being moved in the' opposite 110 direction, the bar V1 Willfirst be slid by itself into the inner part of the grate body. The partV1 Will then carry the part V2 along` with it, through the stop bars l,2 engaging with one another, until the part V2 rests against the stopmember Z- In this position the parts V1 and V2 Will completely lilly theopening in the body of the grate, On the part V1 reaching this extremeposition the tooth 0 on the bar T Will come against the insideof theshield r so that the bar T cnn again be coupled to the body of the gratein the manner already described.

That I claim is: i

1.. A shaking grate for furnaces7 comprising inY combination a gratebody, stationary bearers for supporting the `grate body, means formoving the grate body longitudinally and. laterally on the saidlbearers, a elinlerremovingVv grate capable of sliding in. the said gratebody and arcuate surfaces onthe under side'of the grate bodywhere itrests on the saidbearers, for the purpose. when the grate `body is movedlongitudinally and laterally for also imparting to it a Vertical motionas and for the purpose set forth.

2.. A shaking grate for furnaces .Comprising in Combination a gratebody, stationary bearers for supporting; the grate body. a bar forremovingl the grate body longitudinally and laterally on'the saidbearers, clinkerremoving grates', a` plurality of superposed guides on'the' under side of' the in which the @linker-reniovinggrates can slideone over theV other longitudinally7- the said bar being operablyconnectedl with the clinlielremoving grates means for releasably fixingthe bar to the grate body and., arcuate. surfaces on the under side ofthe grate body.
